Removing sweat marks of white clothes?

How can I remofe the yellow/brown sweat marks off my brothers taekwondo uniform?





i have sprayed the underarms with pre wash spray each time i wash, i pause the washing machine to allow it to soak...


I am not sure about bleaching the whole top, because it has coloured badges that i don%26#039;t want faded or to lose their colour.





Can anyone help me with any suggestions, please...
Removing sweat marks of white clothes?
Yellow underarm shirt stains are likely caused by a combination of deodorant and perspiration. Many deodorants and antiperspirants contain aluminum salts. When these salts are combined with laundry detergent, especially in cooler water settings, they are not easily dissolved, and they remain on the fabric.





To remove the stains, try soaking the shirts in warm water with an enzyme pre-soak product or rubbing the soiled area with white vinegar. Wash in the hottest water safe for the fabric. If the stain remains, dampen and sprinkle stain with meat tenderizer. Let stand for about an hour, and launder again.





To avoid new stains from forming, always wash the shirts in the hottest water safe for the fabric. Also, allow antiperspirant to dry completely before dressing:)

Shampoo or ivory soap with a toothbrush. Those are made to clean body soil and that is what I used for my husbands ring around the collar. Bleaching is a mistake as it not only ruins the patches but will yellow the fabric more. There is a product at the Dollar Store called M30. It comes in a small tub and is a sort of balm. You can use that with a toothbrush as well. It gets lots of stains out even blood. Despite popular belief, you should wash it in cold water as hot sets the stains and fades the patches.
Reply:I read somewhere that sweat stains can be removed by soaking garment in half warm water and half Vinegar.Make sure water isn%26#039;t too hot.I would say half a bucket, and about 3 Tablespoons of ordinary Vinegar. Good Luck!
Reply:sometimes it is the deodorant that is leaving the stains....put your deodorant on and let it dry before getting dressed.....i put mine on as soon as i get out of the shower
Reply:Use a colorsafe bleach, to bleach out or discolor the stain without discolorizing the colored parts.
Reply:Soak overnight in NAPPY-SAN
Reply:I use oxy clean and laundry soap. Soak it overnight in a mixture of both. In the morning add more of it to the stain itself then scrub and wash it with more of the same. It worked wonders on my daughters white soccer uniform on old sweat stains.
